Application September 29, 1931 Serial No. 565,895 7 9 Claims. (CI. 20-16) This invention relates to brackets and pulleys and is designed particularly use in garage doors of the type shown in my Patent No. 1,804,329.

with a view, to its recent The object of the invention is to provide means for supporting door operating weights which will be simpler in operation and easier to install than those shown in the patent referred to.

A further object is to porting door operating provide means for supweights which can be adapted to situations in which the pulleys for supporting weights shown in the patent referred to cannot be used.

Further objects and advantages will become apparent as the description proceeds.

Referring to the accompanying drawings which are made a part hereo f and on which similar reference characters indicate similar parts,

In the patent above r on line 7'-'7 of Figure that shown in Figure 4 different form,

6, and wing theuse of a long acent'the wall of a buildeferred to, the door supporting weights are housed in boxes at the'side of 'the door. Under some circumstances it is difficult to arrange the weights and pulleys in the manner shown in the patent because of the lack of room, since it is necessary to have a box sufficiently wide to accommodate the width of the weight with the necess operation. In cases necessary there is not wide housing or box at the weight. matter of this tions.

In the preferred form ary play to permit free where narrow garages are always room to provide a the side of the door for The brackets forming the subject invention provide for these situaof the invention such as that shown in Figure 1 numeral 38 indicates the side post of a garage or ing a piece 39 of the door.

a door consists of a a horizontal portion 41 preferably being forme other door opening havextending across the top opening The pulley bracket for supporting vertical member 40 and each of these portions d of angle irons which and cross piece and proximately at 45 com une the pulley and may suitably be secured over a corner of the post fastened thereto by bolts 01' screws 42. Secured to or made integralwith the portion 40 is a horizontal bar or bracket portion 43. This bracket portion carries pulleys Y44 and 45 on its opposite ends, these pulleys beingpositioned on opposite sides of the portion'4l. A cable 46 passes over eachof the pulleys and is attached at one end to a collar 61 on a bracket 47 which is secured to or made integral with a plate 48 secured to the side of the door 60. The outer end of the bracket 47 carries a roller 49 which engages suitable guide tracks 50 on the side of the door post. The cable is preferably secured to the collar 61 in the manner. shown in Figure 3. The collar is provided with angular bores 51 which meet and extend the collar at 53. The cable is positioned in these bores and extends angularly through the collar so aslto provide greater friction contact with the the end of the cable is a most efficient and expedient way of securing the cable nevertheless other knotting the endoi the cable or wedgingthe end in the'bores; To

the free end of the cable is attached a weight 55.

In the form shown in Figures 4 and 5 the bracket consists of a short angle portion 10 whichfits over the corner of a post 11. The upper end of the angleportion 10 is flat and is set apwith the sides of the plates forming the angle as shown at 12 and to the portion 12 is mounted a pulley 13 by means of a bolt or rivet 14. The upper portion of the side 12 turns over; at right angles and is formed in the shape of another angle portion 15 which fits under a cross bar 16 above the door. A cable 17 and'52 through the periphery of well known expedients may be employed such as passes over' the pulley and is attached at one end to the door and to the other end is attached a weight 18. 1

From the arrangementshown in Figure 5 itwill be seen that the space at 19 is too small to acthe weight 18. By positi'oning the'pulley 13 at a 45 angle" to the door it is possible to position the weight 18 in front of the boxing 13 inwhich position there is room. ,Ifthe'pulley 13 were positioned in a plane necessary to have a boxing l3 atleastthe full width of the diameter of the pulley. 'By the arrang'ement shown it will be seen that less space parallel to the plane of the door it would be of this form than was necessary with that shown in the patent referred to.

When it is desired to mount double doors there is not sufficient room between the doors to house two brackets with their pulleys. The arrangement shown in Figures 6 and 7 provides for this situation. In this form of mounting the bracket shown in Figures 4 and 5 is mounted as shown to support one of the doors, with the weight 20 enclosed in a boxing 21. A bracket is attached to the other side of the boxing 22 and this bracket consists of a horizontal bar 24 attached to a plate 25 which plate is secured to the door jamb. The bar 24 is preferably positioned at an oblique angle with respect to the plate 25 so that it extends away from the edge of the door 26. A supporting leg 27 is pivoted to the underside of the bar at 28 and is hinged to a base 29 which base is secured to the door posts. Pulleys 30 and 31 are pivoted in the bar. The bar preferably consists of two sides which are separated to permit the pulleys to be pivoted between them. The bar 24 may be made up of a single piece or if preferred the two sides may be separate and suitably riveted orbolted together. In the form shown they are made as a single piece. A cable 32 is attached at one end to the door and has a weight 33 suspended to the other end, the cable preferably passing through a slot 34 in the leg 27. As may be seen in Figure 4 the bar 24 extends out well beyond the weight 20 so that the weight 33 may be positioned in a box 35 beyond the weight 20. Both of the weights may be positioned in the space between the edges of the double doors by this arrangement. Figure 8 shows the use of the long bracket against the side Wall 36 of a building.

Under such circumstances there is not always room enough to accommodate a bracket such as that shown in Figures 4 and 5. As here shown the bar 24 is attached to the cross strip from which the door is suspended. The lower leg 27 rests against the door jamb and the weights are suspended so that they swing over adjacent the wall 36. This provides easy arrangement for supporting the doors where there is not sufficient space to accommodate a housing in which the weights and pulleys may be encased such as is necessary with the arrangement shown in the patent referred to. From the description given it will be seen that the brackets and pulleys of the present invention provide convenient arrangement for balancing and operating the doors when there is not sufficient space to instal. the form shown in the patent referred to..

It will be obviousto those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself 'to what is shown in the drawings anddescribed in the specification, butonly as indicated by the appended claims.
